No amount from submission if select option contains single quote

[rvdsteege]

Our integration is unable to get the amount from a select field option if the option name contains a quote (').

For example, the 2nd option of the following field would not work as expected:

[select* select-123 pronamic_pay_amount "Test|10" "Test's|20"]

The POST'ed value in https://github.com/pronamic/wp-pronamic-pay-contact-form-7/blob/3.0.1/src/Pronamic.php#L82 results in Test's, instead of Test's. This value is later checked against the option names, but with the encoded quotes there is no match with any of the options.
